MECHANICAL

The Mechanical team at Malloy continues to provide application specific mechanical solutions. Our staff is exceedingly qualified to deal with all aspects of the Power Transmission Industry ranging from bearings and gearboxes, to all other forms of power transmission. At Malloy, our mechanical team is trained to assist with selection based on application and customer need. Our inventory is available 24 hours a day, every day to significantly reduce any downtime. The mechanical group will work with customers to develop inventory levels that will keep their process moving with minimal delays.


Malloy provides many services including:


Dynamic Balancing of rotating equipment either in our service shop locations or on site at the customer’s facility with our portable balancing unit.

Shaft alignment to properly align equipment.  Shaft alignment decreases mechanical wear on bearings and seals, and cuts down on overall vibration, decreases energy costs by reducing power consumption, which continually lowers electric utility cost throughout the useful life cycle of the machine.
In-house custom Machining Facilities.

Highly qualified and degreed Mechanical Engineering Team to assist in meeting the requirements for your specific applications.

Machine condition vibration analysis to accurately and reliably diagnose running conditions and save the customer’s facility lost production capacity.

We are committed to providing high quality manufactured products to meet all mechanical needs!

Services

  • The FaroArm is a portable coordinate measuring machine. It measures points in 3D space with respect to a stationary base. The repeatable accuracy of this unit is to 1/3 the diameter of a human hair (0.0011in).

    Used for:

    • 3D Inspections

    • CAD Comparisons

    • Reverse Engineering

    • Dimensional Analysis (cylindricity, concentricity, true point, etc.)

    • Alignment (multi-axis, planar, true-position)

    Malloy has a specific trained staff to operate and interpret the results from our Coordinate Measuring Machine.

  • Malloy offers a highly qualified staff to properly select the products that will meet your specific application. Our mechanical engineering team has extensive knowledge of the products we sell.

    Our team performs technical presentations of products on site and at our training facilities. Trouble shooting complex mechanical systems is done on a regular basis, demonstrating our technical knowledge of how the products solve specific customer problems. Malloy’s mechanical department can select the proper items that will meet the requirements of any system. Some of those items include:

    • Bearings

    • Chain & Sprocket Drives

    • Gear Motors

    • Gear Reducers

    • Shaft Couplings

    • Synchronous Drives

    • V-Belt

    By combining our experience in machine services and the large inventory of replacement parts, we can keep operations running smoothly with the least amount of down time possible!

  • Malloy’s custom machining facility repairs machinery and equipment used in construction, rock quarries, food processing and many other industries. Besides fabrication of special parts, Malloy is able to offer a wide variety of services including:

    • Horizontal boring

    • Lathe machining

    • Milling

    • Planning

    • Shaping

    • Surface grinding

    We also offer more specialized options such as Spray Coating for repair of bearing journals and seal surfaces. For your convenience, several of our services can either be done in the shop or right on site. We offer other services such as the following:

    • Dynamic balancing

    • Portable boring

    • Portable keyway and drilling

    • Precision motor alignment

    • Shaft alignment

    Malloy makes sure to also stock materials for fabrication and repair to help us get the procedure done in a timely manner. Some of those materials include:

    • 4140 hot roll shafting

    • Aluminum

    • Brass

    • Cold rolled flat

    • Cold rolled square

    • Key stock

    • Stainless steel round

    • Stress proof shafting

    • Turn, ground, polished and metric shafting

  • Having a well-balanced machine will help reduce wear and tear on equipment in addition to increasing the life cycle of the machine train. Malloy offers dynamic balancing of rotating equipment, either in our service shop locations or on site at the customer’s facility with our portable balancing unit. We can balance equipment – up to 20,000 pounds – to ISO G1 or less.

    Malloy can single plane or dual plane balancing and a variety of different items including:

    • Chillers

    • Cutter shafts or choppers

    • Industrial and fans

    • Motor rotors

    • Other various rotating equipment

    • Pumps

    Our computer integrated process helps ensure that the job is done accurately. We provide an electronic (PDF) balance report that displays before and after results with every completed job.

    The dynamic balancing process will help save money and keep equipment in working order for years to come!

  • Detection of Electrical Discharges in Bearings

    Overview: Since the 1990’s, the use of Variable Frequency Drives (VFDs) in industry has increased dramatically, mainly for reducing electricity costs. Manufactures have contributed to this development by making VFDs better and more affordable by introducing Pulse Width Modulation drive types. But along with this technology, more premature bearing failures have occurred, and consequently more and more electric motors fail prematurely. Electrical erosion is the cause of these premature failures.

  • Precision alignment has been proven to prolong the life of bearings in electric motors and the equipment they drive. Good alignment decreases mechanical wear on bearings and seals, and cuts down on overall vibration. Properly aligned equipment decreases energy costs by reducing power consumption, which continually lowers electric utility costs throughout the useful life cycle of the machine.

    Laser alignment uses visible beams to acquire critical measurements of a motor position relative to the position of another machine. Our double reverse indication process uses precision lasers in place of dial indicators. Along with built-in, soft foot detection – to allow for proper diagnosis of your systems – lasers are attached to each shaft and a handheld computer to tell our technicians exactly how much correction is needed. Malloy’s technical services group will come to the business site and use these methods to precisely align motors, compressors, fans and various other drive equipment throughout several industries.

    Laser shaft alignment helps put less stress on components and will result in a more reliable production facility and longer asset life!

  • Vibration analysis should be an integral part of your successful maintenance program. Machine condition analysis can accurately and reliably diagnose running conditions and save the customer’s facility thousands of dollars in lost production capacity, lost man hours and scrapped materials. Malloy’s trained and experienced technical services staff can give “spot checks” or plant wide vibration analysis – providing insight on the condition and reliability of your machines.

    Vibration Analysis allows for:

    • Acceptance of new equipment.

    • Avoiding costly trial and error corrective maintenance.

    • Avoiding costly unnecessary routine maintenance.

    • Identifying and correcting ongoing problems.

    • Maintaining quality control.

    • Predicting potential failures.

    • Scheduling equipment downtime.

    The reliability of production equipment is important, so make sure to be informed before daily operations have been affected and use Vibration Analysis!
